I have a Gigabyte RX 470 on Arch Linux. The mainline kernel `amdgpu` driver works fine with only minor issues on Xorg. My current setup is a RX 470 with two LG27UD58s via DisplayPort and 4k@60Hz works fine. I do mostly desktop productivity stuff, but have fired up games briefly(Dota2, Cities: Skylines). There are RX 460 variants that are fanless and can be had for a good price with the RX 500 series release. Known issues: * DisplayPort + HDMI audio bitstreaming is in the 4.11 kernel, I believe I saw the ALSA audio devices on a 4.11 release candidate I ran briefly for another issue. * HDCP isn't implemented yet (can't confirm though) * FreeSync isn't implemented yet (can't confirm either, not sure of the utility other then gaming and maybe video vsync improvements) Follow the news @ http://www.phoronix.com/scan.php?page=search&q=AMDGPU http://www.phoronix.com/scan.php?page=search&q=AMDGPU The "AMDGPU" driver is the OSS and the AMDGPU-PRO is the proprietary driver. Side note, I moved from the Radeon 6870 I bought years ago (or Bitcoin mining, I have two blocks in the chain to that card's credit... a different time). I dropped it not for performance but for deprecated driver support because of the the `radeon` driver. Review this table[1] and try to pick a card that falls under the `amdgpu` driver to avoid support issues in years to come.
